Abstract: ABSTRACT OF THE DISCLOSURE         The recording element of an electrophotograpic copier is provided with a plurality of equally spaced timing marks or other indicia along one edge thereof. Sensing means, positioned adjacent to the path along which the recording element is advanced during the electro-photographic copying process, act to sense the passage of the marks and to generate signals from which the position of each image area of the recording element can be accurately determined.  The output signals from the sensing means are fed to a logic and control apparatus (e.g. a programmed digital computer) which controls  the activation of the various processing stations in timed relation with the receipt of signals.

Abstract: IMPROVEMENTS IN OR RELATING TO   INTERNAL COMBUSTION ENGINES                ABSTRACT OF THE DISCLOSURE           An internal combustion engine of the kind in which combustion is initiated in a first working fluid charge which is then brought into communication with a previously at least substantially separated fuel charge to effect ignition of the second charge.  The invention is characterised in that turbulance is created in the first charge as ignition thereof takes place.  The engine combustion chamber has a cavity of somewhat spherical or cylindrical configuration in which the first charge is ignited.  This cavity has a curved substantially re-entrant surface and the engine is provided with a tangentially disposed channel communicating with the cavity and through which the first working fluid charge is ejected to enter the chamber so as to strike this surface to execute a rotational movement and thereby cause the turbulence.

Abstract: APPARATUS AND METHODS FOR A STEPLESSLY VARIABLE COMPRESSION OF DIGITALLY STORED DATA SEQUENCES WHOSE ABSOLUTE AMOUNT VARY WIDELY FOR SUBSEQUENT VISUAL DISPLAY AND MONITORING                      PURPOSES                  (D ?? 71,200-DTA-97) ABSTRACT          The apparatus and method provides for an improvement to a system which converts wide amplitude range digital data recorded in floating point digital word form to analog signals within a limited amplitude range.  The apparatus and method provides for the situation wherein the digital data can re-present an analog signal for which on a general decrease in amplitude increases may be superimposed.  The apparatus includes a digital/analog converter whose reference voltage is individually determined for each sample.  This reference voltage is taken from a saw tooth oscillator at an instant of time determined by a delay timer which responds to changes, with respect to a desired average amplitude, of the actual amplitude of the converted data.

Abstract: ABSTRACT OF THE DISCLOSURE         A process is described for the production of a stable dispersion of a copolymer, in particular of a copolyester, copolyamide or copolyesteramide, in a non-solvent organic liquid.  The process involves the steps of (1) dispersing two or more comonomers, each of which is capable of undergoing homopolymerisation and is solid at the copolymerisation temperature, in the liquid with the aid of a defined monomer-stabilising agent and so as to produce monomer particles no larger than 50µ, and (2) heating the dispersion so obtained so as to bring about copolymerisation, in the presence of a defined polymer-stabilising agent.  The copolymers so produced are believed to be different in structure from those obtained from the same comonomers by melt or solution copolymerisation.

Abstract: ABSTRACT OF THE DISCLOSURE        The specification describes an accordion folding door or other closure comprising a plurality of vertical panels of extruded material each having a longitudinally continuous male hinge element along one vertical edge thereof and a longitudinally continuous female hinge element along the other vertical edge thereof with each panel being of unitary, one-piece construction.  The hinge elements and panels are arranged so that during movement of the door from the extended to retracted position, adjacent panels fold in a zig-zag manner relative to each other.  The hinge elements are so constructed that inter-connection and separation of the panels is attained by longitudinal sliding movement of the male and female hinge elements in relation to each other.  A locking means is provided in the form of a projecting means associated with the female hinge element which engages with recess means associated with the male hinge element to block relative longitudinal movement between interengaged panels while permitting relative pivotal movement between interengaged panels.  The locking means includes a structure connected with, mounted on or otherwise associated with the female hinge element so that it is stationary in relation thereto and includes a projection which extends into a recess, groove, slot, or similar structure in the male hinge element.          The female hinge element is of generally channel-shaped configuration and is constructed of plastic material having sufficient resiliency and flexibility to enable deflection thereof sufficient to enable assembly and disassembly of adjacent panels by longitudinal sliding movement relative to each other after the locking means is assembled with the channel-shaped female hinge element.

Abstract: CONTROL SYSTEM FOR INDUCTIVELY CONTROLLED                     MULTIPHASE MOTOR          Abstract of the Disclosure The present invention relates to a controller which moves an inductively controlled multiphase motor in a forward or reverse direction.  The motion may be in steps or it may be a continuous rotation.  A microprocessor under the control of a ROM operates through an integrated input/output device to provide control signals for the motor.  A high level current is applied to the motor and is switched from phase to phase thereby causing the motor to rotate in a desired direction.  The time between switching instants is preselected to result in a desired rotation velocity.  When it is desired to stop the continuous rotation of the motor, the times between switching instants are gradually increased, thereby causing the motor to decelerate to a smooth stop.
